Caterpillar GC45K SWB Forklift Engine Service and Schematic Manual (99739-82110)

A Cat GC-series truck moves pallets, trailers, and materials around a warehouse or yard, with the engine doing the heavy work behind the counterweight. In my shop, technicians reach for this manual when they need to test, adjust, tear down, or rebuild the engine instead of guessing from general specifications. This is the engine book of the set, covering GC35K, GC40K, GC45K SWB, GC45K, GC55K, GC60K, and GC70K trucks. GC45K SWB serial coverage is AT87B-00001-up.

What this manual helps you do

  • Check engine specifications, system operation, torque values, and service clearances.
  • Diagnose engine faults through testing procedures and adjustment steps.
  • Follow disassembly and assembly procedures for engine components.
  • Rebuild engine assemblies with the proper inspection and service sequence.
  • Verify adjustments and return the engine to working order after repair.

Who this is for

This suits warehouse maintenance technicians, dealer technicians, independent forklift shops, plant maintenance crews, and rental fleet mechanics. The companion chassis manual, also available, handles the truck chassis, hydraulics, mast, power train, steering, brakes, and related systems.

FAQ

Q: What do I receive, and how is it organized?

A: You receive a 9-publication set delivered as 119 PDF files totaling 2,822 pages, split by section. The PDFs can be searched, copied from, printed, and zoomed for shop use.

Q: Will it fit my truck variant?

A: Yes, when the truck is one of the listed GC models, including GC45K SWB serial AT87B-00001-up. The model coverage is printed from Caterpillar's own publication data.

Q: How does this fit the repair job I'm doing?

A: Use it for engine diagnosis, measurements, adjustments, teardown, assembly, and service specifications. Around my shop, that's the book a mechanic opens when the engine needs real repair work, not just daily operation instructions.

With this set, you can work through the engine repair properly and keep the matching chassis documentation alongside it for the rest of the truck.
